What is a CID?

CID lock (aka vendor lock): Carrier Id - put on your device by the manufacturer to prevent installation of a ROM not released by them. Commonly used in the form `CID-Unlocking`. If you purchase your phone (example) from 3Mobile (3Mobile is the ‘carrier’), your phone will only accept 3Mobile ROMs (the carrier’s ROMs). If you want to flash ROMs from other carrier, you’ll need to CID-unlock your phone, so that your phone will accept other ROMs. All bootloaders (apart from HardSPL and SSPL) will only allow a ROM with the correct CID to be flashed onto the device. A device which has been CID unlocked will have ‘SuperCID’ which allows ANY ROM to be loaded onto the device, SuperCID also unlocks the Ext_ROM and allows it to be mounted. Note: In general, the phrase ‘unlock your phone’ usually refers to SIM-unlock, not CID unlock.


What is Super CID?

SuperCID : by CID unlocking your device the value of the CID is changed to SuperCID . This allows the flashing of ANY ROM/RUU to the device regardless of the carrier and also unlocks the read/write capability of the Ext_ROM.

One the HTC One M7, Super CID is stored in 2 different locations now and that fastboot forcing the new CID does not fully finish the task so you will also need to do the following to complete the task your self.

Thanks to cyber6 from XDA for this guide

You do this at your own risk!!! This could turn your new phone into a very expensive paperweight!!! If you don't know how to do it or are uncomfortable DON'T DO IT!!!

You need ADB and an understanding of how to use it and have a rooted device. You will also need a hex editor like HxD.

1. Fire up your command prompt and go to the directory that you have ADB installed to. Type "adb shell" and hit enter.

2. Type "su" and hit enter. You now have root privileges.

3. Next type "dd if=/dev/block/mmcblk0p19 of=/sdcard/mmcblk0p19" and hit enter. This will dump the partition to your sdcard.

4. Next type "exit", hit enter, type "exit", and hit enter again. This should take you back to a command prompt for your computer.

5. type "adb pull /sdcard/mmcblk0p19" and hit enter. NOTE THE SIZE OF THE FILE BEFORE THE NEXT STEP!

6. Open the file (mmcblk0p19) with your hex editor. DOWNLOAD HEX Editor for Windows

7. Look for offset 00000000 and you should see your CID

8. Change CID to 11111111 and save the file as mmcblk0p19MOD. This will give you SuperCID as well. MAKE SURE AT THIS POINT THAT THE FILE IS THE EXACT SIZE IT WAS BEFORE YOU HEX EDITED IT!

9. Now go back to your command prompt and type "adb push mmcblk0p19MOD /sdcard/mmcblk0p19MOD" and hit enter.

10. Type "adb shell" and hit enter then type "su" and hit enter again. This will put you back into the android shell and give you root privileges.

11. Type "dd if=/sdcard/mmcblk0p19MOD of=/dev/block/mmcblk0p19" and hit enter. To test if it worked restart the phone into fastboot (type "adb reboot bootloader" and hit enter) and once the bootloader screen comes up type "fastboot oem readcid" and hit enter. It should read "11111111".

12. Next type "fastboot reboot" and hit enter. After the phone rebooted open command line and type "adb shell getprop ro.cid" and you
can see the supercid
